Why not? Rotor is just magnet poles swung past the stator coils. The phases come from the coil arrangement not the magnets. More magnets better than fewer unless their flux over laps a coil to pull and push electrons opposite at once nullifying current flow. If you luck out may be able to have it work like a magneto, each swing of magnet by a coil give a jolt of juice just when the points open or trigger signal hits so coil is already charged, batteryless. Maybe just a condensor would do it like a tiny battery, as factory intended. Main thing is a rectifier regulator to match single phase. I'm not sure but I bet the rotors are the same just stators changed as model upgrades and after market.
